GOVERNMENT RIGHTS

This invention was made with government support awarded by The National Institutes of Health. The U.S. Government has certain rights in this invention.

These compounds, including derivatives of erythromycin A, are used and exhibit desirable activity against a number of Gram-positive pathogens. It is also well known that the widespread use of antibiotics over the past 70 years has resulted in the development of a host of antibiotic-resistant pathogens. Numerous examples of resistant infections have been documented in both the hospital and community settings. The present clinically used macrolide antibiotic compounds may be ineffective against these emerging resistant mutants. Therefore, it is of critical importance to develop and provide new drugs with broad-spectrum activity, particularly against drug-resistant strains.

Erythromycin A is a 14-membered macrolactone with good activity against many Gram-positive bacteria. Resistance to this class of antibiotics has been observed however, occurring by one of three mechanisms: (1) inactivation of the drug by chemical modification, (2) target modification such as ribosomal methylation (known as MLS_(B)) or (3) by macrolide efflux. Furthermore Erythromycin A loses activity in acidic media and the decomposition products can give rise to gastric intolerance in many patients.

A second generation of macrolides, also natural products, contain a 16-membered ring e.g. spiramycin, first described in 1956 (G.B. Pat. No. 758,726). The 16-membered macrolides are also acid susceptible. Clarithromycin (U.S. Pat. No. 4,331,803) and azithromycin (U.S. Pat. No. 4,474,768) exemplify a third generation of macrolides. They are semi-synthetic derivatives of Erythromycin A, which overcome the problem of acid instability by preventing the formation of a 6,9-hemiketal by methylation of the 6-hydroxyl in the case of Clarithromycin and by the conversion of the 9-ketone to a tertiary amine in the case of Azithromycin.

Recently, a new class of macrolide compounds has been disclosed, namely, ketolides. Representative examples include telithromycin (U.S. Pat. No. 5,635,485) and ABT-773 (U.S. Pat. No. 6,028,181), which are designed particularly to combat respiratory tract pathogens that have acquired resistance to macrolides. The ketolides are semi-synthetic derivatives of the 14-membered macrolide erythromycin A. The preparation of these ketolides is disclosed in J. Med. Chem., 2000, 43, P. 1045. Current Microbiology, 2001, 42, P. 203. Bioorganic & Medicinal Chemistry Letters, 2000, 10, P. 2019. U.S. Pat. No. 6,420,535 and WO patent No. 99/21866. Ketolides are acid-stable and highly potent against most Gram-positive bacteria and do not induce MLS_(B) resistance.

However, bacterial strains resistant to existing macrolides are being continually isolated and so there is an urgent need to identify new derivatives with improved activity against both Gram-positive and Gram-negative organisms and with superior resistance profiles.

DEFINITIONS

The compounds of the invention comprise asymmetrically substituted carbon atoms. Such asymmetrically substituted carbon atoms can result in the compounds of the invention comprising mixtures of stereoisomers at a particular asymmetrically substituted carbon atom or a single stereoisomer. As a result, racemic mixtures, mixtures of diastereomers, as well as single diastereomers of the compounds of the invention are included in the present invention. The terms “S” and “R” configuration, as used herein, are as defined by the IUPAC 1974 Recommendations for Section E, Fundamental Stereochemistry, Pure Appl. Chem. (1976) 45, 13-30.

The term “treating” as used herein, unless otherwise indicated, means reversing, alleviating, inhibiting the progress of, or preventing the disorder or condition to which such term applies, or one or more symptoms of such disorder or condition. The term “treatment” as used herein, refers to the act of treating, as “treating” is defined immediately above.

The compositions containing the compound(s) of the invention can be administered for prophylactic and/or therapeutic treatments. In therapeutic applications, the compositions are administered to a patient already suffering from an infection, as described above, in an amount sufficient to cure or at least partially arrest the infection and/or its symptoms. An amount adequate to accomplish this is defined as “therapeutically effective amount or dose.” Amounts effective for this use will depend on the severity and course of the infection, previous therapy, the patient's health status and response to the drugs, and the judgment of the treating physician. In prophylactic applications, compositions containing the compounds of the invention are administered to a patient susceptible to or otherwise at risk of a particular infection. Such an amount is defined to be a “prophylactically effective amount or dose.” In this use, the precise amounts again depend on the patient's state of health, weight, and the like.

Once improvement of the patient's conditions has occurred, a maintenance dose is administered if necessary. Subsequently, the dosage or the frequency of administration, or both, can be reduced, as a function of the symptoms, to a level at which the improved condition is retained. When the symptoms have been alleviated to the desired level, treatment can cease. Patients can, however, require intermittent treatment on a long-term basis upon any recurrence of the disease symptoms.

In general, a suitable effective dose of the compound of the invention will be in the range of 0.1 to 5000 milligram (mg) per recipient per day, preferably in the range of 1 to 1000 mg per day, more preferably in the range of 10 to 200 mg per day. The desired dosage is preferably presented in one, two, three, four or more subdoses administered at appropriate intervals throughout the day. These subdoses can be administered as unit dosage forms, for example, containing 5 to 1000 mg, preferably 10 to 100 mg of active ingredient per unit dosage form. Preferably, the compounds of the invention will be administered in amounts of between about 1.0 mg/kg to 250 mg/kg of patient body weight, between about one to four times per day.

The chain may be alkyl, alkenyl, alkynyl, heteroalkyl, heteroalkenyl, or heteroalkynyl, aromatic, conjugated, branched, unbranched, substituted, cyclic, or combinations thereof. If part of a linker and that linker comprises one or more rings as part of the core backbone, for purposes of calculating chain length, the “chain” only includes those carbon atoms that compose the bottom or top of a given ring and not both, and where the top and bottom of the ring(s) are not equivalent in length, the shorter distance shall be used in determining chain length. As noted above, the carbon chain may also contain one or more heteroatoms, i.e., atoms other than carbon. If the chain contains heteroatoms as part of the backbone, those atoms are not calculated as part of the carbon chain length.

The substituents of an “optionally substituted” group may include, without limitation, one or more substituents, more typically one to four, independently selected from the following groups or designated subsets thereof: alkyl, alkenyl, alkynyl, heteroalkyl, haloalkyl, haloalkenyl, haloalkynyl, cycloalkyl, aryl, heteroaryl, arylalkyl, heteroarylalkyl, alkoxy, aryloxy, haloalkoxy, amino, alkylamino, dialkylamino, alkylthio, arylthio, heteroarylthio, oxo, carboxyesters, carboxamido, acyloxy, H, F, Cl, Br, I, CN, NO₂, NH₂, N₃, NHCH₃, N(CH₃)₂, SH, SCH₃, OH, OCH₃, OCF₃, CH₃, CF₃, C(O)CH₃, CO₂CH₃, CO₂H, C(O)NH₂, pyridinyl, thiophene, furanyl, indole, indazole, esters, amides, phosphonates, phosphates, phosphoramides, sulfonates, sulfates, sulfonamides, carbamates, ureas, thioureas, thioamides, thioalkyls. “Substituted aryl” and “substituted heteroaryl” preferably refers to aryl and heteroaryl groups substituted with 1-3 substituents. Preferably these substituents are selected from the group consisting of lower alkyl, lower alkoxy, lower perhaloalkyl, halo, hydroxy, and amino. An optionally substituted group may be unsubstituted (e.g., —CH₂CH₃), fully substituted (e.g., —CF₂CF₃), monosubstituted (e.g., —CH₂CH₂F) or substituted at a level anywhere in-between fully substituted and monosubstituted (e.g., —CH₂CF₃).

The term “halogen” includes F, Cl, Sr and I.

The term “isomeric mixture” means a mixture of two or more configurationally distinct chemical species having the same chemical formula. An isomeric mixture is genus comprising individual isomeric species. Examples of isomeric mixtures include stereoisomers (enantiomers, diastereomers), regioisomers, as might result for example from a pericyclic reaction. The compounds of the present invention comprise asymmetrically substituted carbon atoms. Such asymmetrically substituted carbon atoms can result in mixtures of stereoisomers at a particular asymmetrically substituted carbon atom or a single stereoisomer. As a result, racemic mixtures, mixtures of diastereomers, as well as single diastereomers of the compounds of the invention are included in the present invention. The terms “S” and “R” configuration, as used herein, are as defined by the IUPAC 1974 Recommendations for Section E, Fundamental Stereochemistry, Pure Appl. Chem. (1976) 45, 13-30.

The methods disclosed in the present invention may result in the preparation of different regioisomers and or stereoisomers. This event is not intended to lessen the usefulness of the presently disclosed methods, rather isomeric mixtures may be more readily tested than separated isomeric species. Easily prepared mixtures of two or more stereoisomers or regioisomers may be separated if testing of isomeric mixtures indicates that one or more active species is present.

Prodrugs

The term “prodrug” as used herein refers to any compound that when administered to a biological system generates a biologically active compound as a result of spontaneous chemical reaction(s), enzyme-catalyzed chemical reaction(s), and/or metabolic chemical reaction(s), or a combination of each.

Standard prodrugs are formed using groups attached to functionality, e.g. HO—, HS—, HOOC—, R₂N—, associated with the drug, that cleave in vivo. Standard prodrugs include but are not limited to carboxylate esters where the group is alkyl, aryl, aralkyl, acyloxyalkyl, alkoxycarbonyloxyalkyl as well as esters of hydroxyl, thiol and amines where the group attached is an acyl group, an alkoxycarbonyl, aminocarbonyl, phosphate or sulfate. The groups illustrated are exemplary, not exhaustive, and one skilled in the art could prepare other known varieties of prodrugs. Such prodrugs of the compounds of Formula 1 and Formula 2 fall within the scope of the present invention. Prodrugs must undergo some form of a chemical transformation to produce the compound that is biologically active or is a precursor of the biologically active compound. In some cases, the prodrug is biologically active, usually less than the drug itself, and serves to improve drug efficacy or safety through improved oral bioavailability, pharmacodynamic half-life, etc. The biologically active compounds include, but are not limited to antibiotic agents, anticancer agents, antiviral agents, and agents for treating gastric motility disorders.

Prodrugs contain a chemical moiety, e.g., an amide or phosphorus group whose function is to endow enhanced solubility and/or stability to the attached drug so that it can be effectively preserved/delivered to a host. Once in the body, the prodrug is typically acted upon by an enzyme in vivo, e.g., an esterase, amidase, or phosphatase, to liberate/generate the more pharmacologically active drug. This activation may occur through the action of an endogenous host enzyme or a non-endogenous enzyme that is administered to the host preceding, following, or during administration of the prodrug. Prodrug use in general is further discussed, e.g., in U.S. Pat. No. 5,627,165, as well as in Pathak et al., Enzymic protecting group techniques in organic synthesis, Stereosel. Biocatal. 775-797 (2000), and is otherwise well known in the art, although not to Applicants' knowledge using the specific compounds and compositions claimed herein.

Ideally, the prodrug should be converted to the original drug as soon as the goal is achieved, followed by the subsequent rapid elimination of the released derivatizing group. The term can also mean a nonspecific chemical approach to mask undesirable drug properties or improve drug delivery. For example, many therapeutic drugs have undesirable properties that may become pharmacological, pharmaceutical, or pharmacokinetic barriers in clinical drug application, such as low oral drug absorption, lack of site specificity, chemical instability, toxicity, and poor patient acceptance (bad taste, odor, pain at injection site, etc.). The prodrug approach, a chemical approach using reversible derivatives, can be useful in the optimization of the clinical application of a drug.

Pharmaceutical Compositions/Formulations, Dosaging, and Modes of Administration

Those of ordinary skill in the art are familiar with formulation and administration techniques, e.g., as discussed in Goodman and Gilman's The Pharmacological Basis of Therapeutics, current edition; Pergamon Press; and Remington's Pharmaceutical Sciences (current edition.) Mack Publishing Co., Easton, Pa. These techniques can be employed in appropriate aspects and embodiments of the invention.

The compounds utilized in the methods of the instant invention may be administered either alone or in combination with pharmaceutically acceptable carriers, excipients or diluents, in a pharmaceutical composition, according to standard pharmaceutical practice. The compounds can be administered orally or parenterally, including the intravenous, intramuscular, intraperitoneal, subcutaneous, rectal and topical routes of administration.

For example, the therapeutic or pharmaceutical compositions of the invention can be administered locally to the area in need of treatment. This may be achieved by, for example, but not limited to, local infusion during surgery, topical application, e.g., cream, ointment, injection, catheter, or implant, said implant made, e.g., out of a porous, non-porous, or gelatinous material, including membranes, such as sialastic membranes, or fibers. The administration can also be by direct injection at the site (or former site) of a tumor or neoplastic or pre-neoplastic tissue.

Still further, the therapeutic or pharmaceutical composition can be delivered in a vesicle, e.g., a liposome (see, for example, Langer, 1990, Science, 249:1527-1533; Treat et al., 1989, Liposomes in the Therapy of Infectious Disease and Cancer, Lopez-Bernstein and Fidler (eds.), Liss, N.Y., pp. 353-365).

The pharmaceutical compositions used in the methods of the present invention can be delivered in a controlled release system. In one embodiment, a pump may be used (see, Sefton, 1987, CRC Crit. Ref. Biomed. Eng. 14:201; Buchwald et al., 1980, Surgery, 88:507; Saudek et al., 1989, N. Engl. J. Med., 321:574). Additionally, a controlled release system can be placed in proximity of the therapeutic target (see, Goodson, 1984, Medical Applications of Controlled Release, Vol. 2, pp. 115-138).

The pharmaceutical compositions used in the methods of the instant invention can contain the active ingredient in a form suitable for oral use, for example, as tablets, troches, lozenges, aqueous or oily suspensions, dispersible powders or granules, emulsions, hard or soft capsules, or syrups or elixirs. Compositions intended for oral use may be prepared according to any method known to the art for the manufacture of pharmaceutical compositions and such compositions may contain one or more agents selected from the group consisting of sweetening agents, flavoring agents, coloring agents and preserving agents in order to provide pharmaceutically elegant and palatable preparations. Tablets contain the active ingredient in admixture with non-toxic pharmaceutically acceptable excipients, which are suitable for the manufacture of tablets. These excipients may be, for example, inert diluents, such as calcium carbonate, sodium carbonate, lactose, calcium phosphate or sodium phosphate; granulating and disintegrating agents, such as microcrystalline cellulose, sodium crosscarmellose, corn starch, or alginic acid; binding agents, for example starch, gelatin, polyvinyl-pyrrolidone or acacia, and lubricating agents, for example, magnesium stearate, stearic acid or talc. The tablets may be uncoated or they may be coated by known techniques to mask the taste of the drug or delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a water soluble taste masking material such as hydroxypropylmethyl cellulose or hydroxypropyl cellulose, or a time delay material such as ethyl cellulose, or cellulose acetate butyrate may be employed.

Formulations for oral use may also be presented as hard gelatin capsules wherein the active ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin, or as soft gelatin capsules wherein the active ingredient is mixed with water soluble carrier such as polyethyleneglycol or an oil medium, for example peanut oil, liquid paraffin, or olive oil.

Aqueous suspensions can contain the active material in admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients can act as suspending agents and include, e.g., sodium carboxymethyl cellulose, methyl cellulose, hydroxypropylmethyl cellulose, sodium alginate, polyvinyl pyrrolidone, gum tragacanth and gum acacia; dispersing or wetting agents may be a naturally-occurring phosphatide, for example lecithin, or condensation products of an alkylene oxide with fatty acids, for example polyoxyethylene stearate, or condensation products of ethylene oxide with long chain aliphatic alcohols, for example heptadecaethylene-oxycetanol, or condensation products of ethylene oxide with partial esters derived from fatty acids and a hexitol such as polyoxyethylene sorbitol monooleate, or condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol anhydrides, for example polyethylene sorbitan monooleate. The aqueous suspensions may also contain one or more preservatives, for example ethyl, or n-propyl p-hydroxybenzoate, one or more coloring agents, one or more flavoring agents, and one or more sweetening agents, such as sucrose, saccharin or aspartame.

Oily suspensions may be formulated by suspending the active ingredient in a vegetable oil, for example arachis oil, olive oil, sesame oil or coconut oil, or in mineral oil such as liquid paraffin. The oily suspensions may contain a thickening agent, for example beeswax, hard paraffin or cetyl alcohol. Sweetening agents such as those set forth above, and flavoring agents may be added to provide a palatable oral preparation. These compositions may be preserved by the addition of an anti-oxidant, e.g., butylated hydroxyanisol, alpha-tocopherol, or ascorbic acid.

Dispersible powders and granules suitable for preparation of an aqueous suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent, suspending agent and one or more preservatives. Suitable dispersing or wetting agents and suspending agents are exemplified by those already mentioned above. Additional excipients, for example sweetening, flavoring and coloring agents, may also be present. These compositions may be preserved by the addition of antioxidant(s).

The pharmaceutical compositions used in the methods of the instant invention may also be in the form of oil-in-water emulsions. The oily phase may be a vegetable oil, for example olive oil or arachis oil, or a mineral oil, for example liquid paraffin or mixtures of these. Suitable emulsifying agents may be naturally-occurring phosphatides, for example soy bean lecithin, and esters or partial esters derived from fatty acids and hexitol anhydrides, for example sorbitan monooleate, and condensation products of the said partial esters with ethylene oxide, for example polyoxyethylene sorbitan monooleate. The emulsions may also contain sweetening, flavoring agents, preservatives and antioxidants.

Syrups and elixirs may be formulated with sweetening agents, for example glycerol, propylene glycol, sorbitol or sucrose. Such formulations may also contain a demulcent, a preservative, flavoring and coloring agents and antioxidant.

The pharmaceutical compositions may be in the form of composition suitable for use as an inhalant.

The pharmaceutical compositions may be in the form of a sterile injectable aqueous solution. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution.

The sterile injectable preparation may also be a sterile injectable oil-in-water microemulsion where the active ingredient is dissolved in the oily phase. For example, the active ingredient may be first dissolved in a mixture of soybean oil and lecithin. The oil solution then introduced into a water and glycerol mixture and processed to form a microemulsion.

The injectable solutions or microemulsions may be introduced into a patient's blood stream by local bolus injection. Alternatively, it may be advantageous to administer the solution or microemulsion in such a way as to maintain a constant circulating concentration of the instant compound. In order to maintain such a constant concentration, a continuous intravenous delivery device may be utilized. An example of such a device is the Deltec CADD-PLUS™ model 5400 intravenous pump.

The pharmaceutical compositions may be in the form of a sterile injectable aqueous or oleagenous suspension for intramuscular and subcutaneous administration. This suspension may be formulated according to the known art using those suitable dispersing or wetting agents and suspending agents which have been mentioned above. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, for example as a solution in 1,3-butane-diol. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.

The macrolides used in the methods of the present invention may also be administered in the form of suppositories for rectal administration of the drug. These compositions can be prepared by mixing the inhibitors with a suitable non-irritating excipient which is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials include cocoa butter, glycerinated gelatin, hydrogenated vegetable oils, mixtures of polyethylene glycols of various molecular weights and fatty acid esters of polyethylene glycol.

For topical use, creams, ointments, jellies, solutions or suspensions, etc., containing a macrolide can be used. As used herein, topical application can include mouthwashes and gargles.

The compounds used in the methods of the present invention can be administered in intranasal form via topical use of suitable intranasal vehicles and delivery devices, or via transdermal routes, using those forms of transdermal skin patches well known to those of ordinary skill in the art. To be administered in the form of a transdermal delivery system, the dosage administration will, of course, be continuous rather than intermittent throughout the dosage regimen.

The methods and compounds of the instant invention may also be used in conjunction with other well known therapeutic agents that are selected for their particular usefulness against the condition that is being treated. For example, the instant compounds may be useful in combination with known anti-cancer and cytotoxic agents.

Preferably the pharmaceutical preparation is in unit dosage form. In such form, the preparation is subdivided into unit doses containing appropriate quantities of the active component, e.g., an amount that is effective to achieve the desired purpose.

The actual dosage employed may be varied depending upon the requirements of the patient and the severity of the condition being treated. Determination of the proper dosage for a particular situation is within the skill of the art. Generally, treatment is initiated with smaller dosages which are less than the optimum dose of the compound. Thereafter, the dosage is increased by small amounts until the optimum effect under the circumstances is reached. For convenience, the total daily dosage may be divided and administered in portions during the day if desired.

The amount and frequency of administration of the compounds used in the methods of the present invention and, if applicable, other chemotherapeutic agents will be regulated according to the judgment of the attending clinician (physician) considering such factors as age, condition and size of the patient as well as severity of the disease being treated.

In general, compounds of the invention and, in embodiments where combinational therapy is employed, other agents do not have to be administered in the same pharmaceutical composition, and may, because of different physical and chemical characteristics, have to be administered by different routes. The determination of the mode of administration and the advisability of administration, where possible, in the same pharmaceutical composition, is well within the knowledge of the skilled clinician. The initial administration can be made according to established protocols known in the art, and then, based upon the observed effects, the dosage, modes of administration and times of administration can be modified by the skilled clinician. The particular choice of compounds used will depend upon the diagnosis of the attending physicians and their judgment of the condition of the patient and the appropriate treatment protocol. The compounds may be administered concurrently (e.g., simultaneously, essentially simultaneously or within the same treatment protocol) or sequentially, depending upon the nature of the proliferative disease, the condition of the patient, and the actual choice of compounds used.

The determination of the order of administration, and the number of repetitions of administration of each therapeutic agent during a treatment protocol, is well within the knowledge of the skilled physician after evaluation of the disease being treated and the condition of the patient.

Preparation of Compounds

The compounds of Formula 1 may be prepared according to Schemes 1 below and the description that follows. All other substituents, including X, Y, R1, R₂, R₃, V and W are as defined in the Summary of the Invention unless otherwise indicated.

The compounds of the invention are readily prepared. Referring to Scheme 1, the starting compounds of Formulas 5 may be prepared from Erythromycin A, according to one or more methods familiar to those skilled in the art including the synthetic methods described by U.S. Pat. Nos. 5,635,485 and 6,028,181, both of which are hereby incorporated by reference.

In step 1 of Scheme 1, the desosamine of Formula 5 is protected using methods know to those skilled in the art to provide a compound of Formula 4; R can be ester protecting group but not limited to ester protecting group. The cleavage of the desosamine sugar forms an aglycone compound of Formula 3. In step 2 of Scheme 1, the compound of Formula 3 is functionalized to form a compound of Formula 1. Wherein R₁ is selected from cyclic and acyclic alkyl, cyclic and acyclic alkyl-hydroxyamine, aryl, aryl-hydroxyamine, cyclic and acyclic acyl, cyclic and acyclic acyl-hydroxyamine, heteroalkyl, heteroalkyl-hydroxyamine, heteroaryl, heteroaryl-hydroxyamine, acylaryl, acylaryl-hydroxyamine, acylheteroaryl, acylheteroaryl-hydroxyamine, alkylaryl, alkylaryl-hydroxyamine, alkylheteroaryl, alkylheteroaryl-hydroxyamine, sulfonylalkyl, sulfonylalkyl-hydroxyamine, acylalkoxylsulfonylalkyl, acylalkoxylsulfonylalkyl-hydroxyamine;

or R₁ can be —C(O)—NR₄R₅, where R₄ and R₅ can be independently or taken together as hydrogen, hydroxy, alkyl, aralkyl, alkylaryl, alkoxy, heteroalkyl, aryl, heteroaryl, dimethylaminoalkyl, acyl, sulfonyl, urea or carbamate and acceptable salts thereof;

or R₁ can also be a monosaccharide (including amino sugars and their derivatives, particularly, a mycaminose derivatized at the C-4′ position or a 4-deoxy-3-amino-glucose derivatized at the C-6′ position), a disaccharide (including a mycaminose derivatized at the C-4′ position with another sugar or a 4-deoxy-3-amino-glucose derivatized at the C-6′ position with another sugar), a trisaccharide (including aminosugars and halosugars), chloramphenicol, clindamycin or their analogs; provided that R₁ can not be desosamine.

Synthesis of the compounds of Formula 1 may comprise other steps in addition to those shown in Scheme 1. For example, groups bonded to R₂ may be modified following derivatization of C5 hydroxy group of formula 3.

Compounds of Formula 2 comprise a heteroaromatic ring linked via a spacer to nitrogen at position 11 around a 14-membered macrolide core. The heteroaromatic ring and spacer are abbreviated “A-B-C”:

An “A-B-C” moiety may be appended to a macrolide scaffold using a variety of methods. Commercially available macrolides bear a number of reactive functional groups, which may be further functionalized after suitable protection of other possible reactive sites. Macrolides that bear nucleophilic functional groups (for example amines and hydroxyl groups) may be treated with an “E-B-T-C” fragment bearing at least one complimentary electrophilic group, E, that T represent 1,4-substituted 1,2,3-triazole moiety. The terms “nucleophilic”, “nucleophile,” “electrophilic” and “electrophile” have their usual meanings familiar to synthetic and/or physical organic chemistry.

Preferred electrophiles of the present invention are carbon electrophiles. Examples of preferred carbon electrophiles include but are not limited to carbonyls (especially aldehydes and ketones), oximes, hydrazones, epoxides, aziridines, alkyl-, alkenyl-, and aryl halides, acyls, sulfonates (aryl, alkyl and the like). Other examples of carbon electrophiles include unsaturated carbons electronically conjugated with electron-withdrawing groups, examples being the β-carbon in α,β-unsaturated ketones or carbon atoms in fluorine substituted aryl groups. In general, carbon electrophiles are susceptible to attack by complementary nucleophiles wherein an attacking nucleophile brings an electron pair to the carbon electrophile in order to form a new bond between the nucleophile and the electrophile.

Preferred nucleophiles suitable for coupling to carbon electrophiles include but are not limited to primary and secondary amines, thiols, thiolates, and thioethers, alcohols, alkoxides. These preferred nucleophiles, when used in conjunction with preferred carbon electrophiles, typically generate heteroatom linkages (C—X—C) between a scaffold and a linker group. Nucleophilic attack by the macrolide nucleophile on a suitably substituted heteroaromatic substrate “B-T-C” bearing a functional group “E”, which contains an electrophilic carbon or sulfur atom, can thus unite the two through the formation of linker “A” (Scheme 2).

Scheme 2

Macrolide−OH+E−B−T−C→Macrolide−O−A−B−T−C

Alternatively, the fragment “A-B-T-C” can be attached to a macrolide scaffold in a stepwise manner such as described below in examples 1-5. Here the heterocyclic ring “T” is a 1,4-substituted 1,2,3-triazole prepared using a Huisgen cyclization, which constitutes the final step of each synthesis. The copper catalyzed Huisgen cyclization has been shown to unite azides and terminal acetylenes regiospecifically to give exclusively 1,4-disubstituted [1, 2, 3]-triazoles (Tornøe et al., J. Org. Chem., 2002, 67, 3057) and this observation was confirmed using NOE experiments carried out on model compounds. Commercially available macrolides were suitably protected and then modified by the attachment of either an azide or an alkyne functional group through a linker or spacer “A-B”. The activated macrolides were then coupled with the fragment “C” which bears the complimentary functional group. The reactions were carried out either solvent-free, in water or in an organic solvent such as acetonitrile or toluene. The reactions were carried out at temperatures ranging from 20 to 80° C. The reaction could be promoted with the use of a catalyst, including but not limited to a transition metal halide (MX_(n)) (Scheme 3).

The term “scaffold” refers to a molecule that provides a molecular framework on which to append another chemical moiety or functional group. An antibiotic scaffold is a scaffold having recognized usefulness as an antibiotic. Appending chemical moieties to an antibiotic scaffold may beneficially alter a number of properties of an antibiotic including, but not limited to, absorption, distribution, metabolism, excretion and toxicity, and efficacy.

The term “unsaturated moiety” refers in general to a moiety comprising one or more π-bonds. Examples of such moieties are optionally substituted alkenes, alkynes, and nitriles. Unsaturated moieties undergo pericyclic reactions with complimentary dienes, heterodienes, and 1,3-dipoles resulting in the formation of 5 and 6-membered ring compounds. 1,3-Dipoles and dienes may themselves be part of an open-chain framework, or part of a ring system, with the exception that they may not be frozen into a transoid configuration.

The term “pericyclic reaction” refers to a family of chemical reactions characterized by bonding changes taking place through reorganization of electron pairs within a closed loop of interacting orbitals. Bonding changes in pericyclic reactions are typically, but not necessarily concerted, that is, bonds break and form simultaneously rather than in two or more steps. Preferred types of pericyclic reactions include but are not limited to cycloaddition reactions. A cycloaddition reaction is a reaction in which two or more molecules condense to form a ring by transferring electrons from π-bonds to new σ-bonds. Examples of such reactions are Huisgen cycloadditions, Diels-Alder and hetero Diels-Alder cycloadditions. A preferred type of cycloaddition reaction according to one embodiment of the invention is a Huisgen cyclization. A Huisgen cycloaddition involves the addition of an unsaturated moiety to a 1,3 dipole, as for example shown schematically below:

Triazoles result when azides add to triple bonds in a Huisgen cycloaddition. A Huisgen cycloaddition is one example of a group of reactions in which five-membered heterocyclic compounds are prepared by addition of 1,3-dipolar compounds to an unsaturated (usually double or triple) bond, the latter also known as a 1,3-dipolaraphile.

When two molecules react to form a cycloadduct, mixtures may result. Obtaining one or more desired cycloadduct when several are theoretically possible is known as stereocontrol. When an unsymmetrical 1,3-dipole adds to an unsymmetrical dipolarophile, there are two possible products (not counting stereoisomers). Although mixtures are often obtained, one may predominate. This regioselectivity may often be explained via theoretical and or calculational considerations.

The invention will be further illustrated by reference to the following non-limiting Examples.
